What we’re calling a compressor could just be moving/ modulating air back and forth from the tank to the springs.

That would be true in a closed system, but then there also wouldn’t be a atmosphere air intake for the pump or a need to purge.

The posted info above indicated both closed and refilling from atmosphere. To me FCA is just misusing the term closed, and nitrogen is used to fill after repairs because it’s drier than compressed air.

Wayne and Others.. I have been contacted NOT to Post Diagrams or any type of the possibility of posting protected info....I break this rule from time to time.. Like I did in the DEF Thread.. but not this one...So I hope members and readers need to understand that professional's honorable People don't leak info that's protected.. I never want to be like The X people in America that have no standards.

I don’t think anyone is suggesting plagiarism here, but I see nothing wrong with explaining the system in your own words, that is if you’re capable.

 

[TCDiesel]

Keystrokes are not My strong point....Plus it seems people just will challenge even the most trivial matters, Couple that with the time it takes I just don't have.

 

[TFucili]

I tried Tech Authority, but it requires Windows and IE. I'm out. I would gladly buy a FSM if they had one. Plus it's "only" $1800 for an annual subscription.

 

[TCDiesel]

Yep, for 2019 You need the Subscription. Hmmm on the $1800.00.......Plus $1600.00 on 2.0 & the MIC II and the setup time..= $$$$$.For all of it.

Its considerably less on the daily Charges , Still Lotaa $$$$

It explains why the tech didn’t seem to know the system, in his words “I’m learning this system as I go”. It has been out for a few years, someone should know something that is not infringing on a patent.

TC, can you not give the sequence of operation, if not just tell us that is classified as well.

 

[TCDiesel]

I know the 1500 Well, its closed, the 2500 and 3500 Not so well..I will investigate....and report back.

When I was on my way from Minot to Az. a guy next to me was bragging about the air system on his new Ram. Now I am a realist so none of this is personal. I told him all that stuff is great until it doesn't work then it's a pain in the butt and maybe expensive to repair. Think I will stick with my Airlifts, yeah I have to inflate/deflate manually but they seem to work everytime for the last 20 or so years. I guess my personal problem with automatic automation is after working on controls for over 40 years is that they seem to break frequently in some way but usually the manual stuff just keeps going.

The system is really closed. The compressor moves air/nitrogen back and forth between the tank and the bags. The reason it has an intake and drier is to make up for any SMALL quantity of lost air. One of the first tests the technician should do is check the air mass. If it is low the system has a leak and is not able to make up for the leak by drawing outside air. If the system has to pull too much outside air it will set a code for low air mass and they usually set a compressor over temp code from running too long. It also is capable of determining leaks in the tank circuit, and each bag circuit individually. It also has faults for plugged/pinched lines because it measures the time it takes to raise/lower the vehicle to the desired height.
If the technician does not know how to perform the leak test there is a very good video in the diagnosis section that explains it.

An RRT is a Rapid Response Transmittal. I guess it is like a higher priority Service Bulletin. I have asked for a copy twice, and they "forget" to do it. It was RRT #19-057.

The RRT was also released as a TSB. It covers trucks built before July. If your ASCM was up to date when the technician checked it, it either didn't apply, or had already been flashed with the latest software. It also didn't address anything that has been complained about in this thread. Also RRT's have to be completed, TSB's only if the customer has the specific concern.

Sounds like one heckuva complex compressor/ control unit.

What is purging at startup then? It’s a small quantity, but happens at every start. Or is the 19 different?

 

[sag2]

I do not believe it is purging, there would be no reason to. It may be replacing some lost air, but I doubt it. If you want to test it, pull the filter off the hose and put your finger over it when you start. See if it sucks or blows.

Thanks for the info. My truck did need it. I can say it definitely changed the ride quality, whether intentional or not. Much like the recall for my 2015 that had nothing to do with the Aux Switches, but they were fouled up by the reflash. This truck rode "impossibly good", and now rides like a 1 ton. Not a complaint, but a change in behavior. Likewise, it did not droop to the left before, and now it does.

There is an audible high pressure air purge every time I start and drive the truck. Dads 17 does the exact same thing.

It does not sound like it’s coming from the air intake.

The compressor also runs while no suspension adjustments are made, and after adjustments are made. Neither of those would be necessary in a closed system.

If your sure that it is running and not changing modes then you have a small leak. The dealer can put it into plant mode and test it for leaks.

So are you saying that it comes charged with nitrogen, but can eventually be replaced with air, what’s the point of even using nitrogen?

I don't know anything about these systems, but the air we breathe is already about 78% nitrogen, so perhaps they deem the small amount of oxygen added to be peanuts.

mine was of the first ones released in 2015. Not even a phart.
